Statistics-driven microbenchmarking for Rust that reliably detects performance changes.
Orama
A dependency-free full-text, vector, and hybrid search engine that runs entirely in JavaScript.
fgprof

Compile-time-checked builder generator and named function arguments for Rust
generic
A collection of type-safe generic data structures for Go, built on Go 1.18 generics with no reflection or interface{} boxing.

spade
Delaunay triangulations and Voronoi diagrams for the Rust ecosystem
radix_trie
A fast, generic radix trie for Rust with compressed nodes and ancestor/descendant prefix lookups.
bimap-rs
Fast, generic bijective maps for Rust that feel like the standard library.
lru-cache
